To all whom it may concern:' Be it known that I, FREEMAN W. H001), a-

citizen of the United States, vresidin g at NeW-* ton, in the county ofMiddlesex andCommonwealth'of Massachusetts, have invented a new anduseful Improvement in Water-Me;

. ters, of which the following is a full, clear,-

and exact description, reference being" h'adto where it passes by theinlet-port c, which port is shown by the dotted line back of theabutment (it.v The natural trend of the piston,due to the direction ofthe current of the water, and

which is the same as the direction of the gymtion of the piston, in,ordinary constructions is against the side of the abutment nearest theoutlet-port, at whichpoint the thrust is received by the slotted edge ofthe piston. In order to relieve this thrust and obviate the" frictionincident thereto, I have widened the face of the abutment back to thepoint marked f, that is, that face which is adjacent to the a ball ofthepiston, indicated by e, and have.

f so that the pin g, which I insert loosely and slotted it perpendicularto the'bottom plate,

radiallyin the ball of the piston, may vibrate freely therein as thepiston gyrates. In this way l aln enabled to out a wide slotiinthepiston, so wide in fact that the slotted edge I does not bear at anypoint on the abutment,

ll-the thrust of the piston being taken up by the pin gin the slot h. Onaccount of the pin- 9 being fitted loosely in the ball, it makes aperfect roller-contact in the slot h and a rotating contact in the ballof the piston. The effect of this-arrangement is to ento greatlyred ucethe friction, and consequently improve the registration and increase thesensitiveness and durability of the meter. To still further decrease thethrust due to currents of waterat high velocity, I have beveledthe edgeof the piston at b, where it passes the-port a, so that the water willnot :face, as in the ordinary construction, but ineither side of'thepiston.

Having thus fully described myinvention, what I. desire to claim andsecure by Letters Patent i s with a disk-chamber and disk, of anabutment provided with a slot in the face thereof adjoining the ball ofthe piston, a pin projecting from the ball of said piston and acting insaid slot, substantially as set forth and described.

In a disk water-meter adisk, a pin, projectin g radially from the centerof the ball of the disk, said pin acting in a slot in the face disk,substantially as set forth and described.

3. In adisk. water-meter a disk,a pinprojecting from the ball of thedisk, said pin being free to rotate in the ball of the disk and rollagainst the side of a slot in the abutment, substantially as set forthand described;
